To all whom t may concern:

Be it known that I, GEORGE WV. KLAGEs, a citizen of the United States,residing `at PittsburghJ in the county of Allegheny and State ofPennsylvania, have invented anew and useful Improvement in Glass-CuttingTables, of which the following' is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of thisspecification, in which:

Figure 1 is a plan view of a glass cutting table embodying my invention.Fig. 2 isa plan view of a portion of the table, partly broken away on alarger scale. Fig. 3 is a side elevation of the table. Fig. 4 is an endview looking at the left hand end of Fig.

1. Fig. 5 is a similar view looking 'at the opposite end. Figs. 6, 7 and8 are detail sectional views taken on the lines Vl-l-VI, V1I-VII andVIII-VH1, respectively, of Fig. 3, and Figs. 9, 10 and 11 are detailsectional views hereinafter more fully described, Fig. 11 being asection on the line X11-XI of Fig. 10.

My invention has relation to glass cutting tables such as are used forcutting plates or sheets of glass of various sizes.

The object of my invention is to provide a table of simple andconvenient arrangement, by means ofwhich plates or sheets can be cut toaccurate sizes as measured in feet or inches or a fraction thereof, or ameasure in accordance with the metric or any other system.

My invention provides a table of this character in which the change fromone system to another can be readilymade without difficulty and withoutthe necessity for any mathematical computation on the part of theoperator.

The nature of the invention in detail will be best understood byreference to the accompanying drawings, in which I have shown thepreferred embodiment thereof, and which will now be described, it beingpremised, however, that variouschanges can be made in the details 'ofconstruction and arrangement ofthe several parts to those skilled in theart, without departing from the spirit and scope of my invention, asdelined in the appended claims. v

Referring to the accompanying drawings,

the numeral 2 designates a `glass cutting" table which may be, ingeneral, of the `usual construction.

3 designates the usual cutting rule which is movable longitudinally ofthe table to the proper position and which forms the straight edge alongwhich the cutting tool is moved to'cut th'egla'ss. This rule may be ofthe usual character.

4 designates a scale plate at one end of the table, having at one edgescale divisions 5 in feet and inches and at the other edge scaledivisions 6 according to the metric system and denoting centimetermeasurement. 7 is another .scale plate extension along one edge of thetable and also having two scales thereon similar to the 'scales 5 and 6.One of these scales is graduated in inches and the other into centimeterspaces. They may, however, be graduated to any subdivision of `anysystem of measurements desired.

The usual table is provided at its edges with a series of gage pins withwhich the cutting rule 3 is yengaged to holdit in its proper positionfor cutting. In' accordance with my invention, I provide at eachlongitudinal edge of the table, two sets of these gage pins, the pins ofthe two sets being properly spaced with reference, respectively, to thetwo scales in the scaleplate'?, and being so arranged thatpeither set,of these pins can be brought into use at will for engagement with therule. The two Vsets of pins at one edge of the table are designated,respectivelyby the numerals 8 and 9, and those at the opposite edge ofthe table by the numerals 10 and 11. The pins 8 and 9 are fixed in alongitudinal bar 12, which is mounted in suitable brackets 13 so as tobe capable of being turned through an angle of 90. The brackets 13 arepreferably carried by a longitudinal plate 111 at the adjacent edge ofthe table which is secured thereto in a manner to admit of somelongitudinal adjustment. The securing means may consist of screws 15passing through oblong slots 16 in the bar 14. The ypins 10 and 11 arecarried by a longitudinal bar 18 Vwhichis mounted for rotation throughan angle of 180o, or through an angle correpins 10 and 11, lso as tobring either set of pins in position for engagement with the end portionof the rule 3.

Tn every case the pins 8 and 9, and 10 and 11, will be spacedrespectively in accordance with the particular systems of measurementsfor which the table is employed.

The bars 12 and 18 can be turned from one position to the other by anysuitable means. T have shown the bar 12 as having a crank arm 19 at oneend portion, with an actuating bar 20 connected thereto and eX- tendingacross the end of the table, to be conveniently accessible, anduwhere itis provided with a suitable actuating knob or handle 21. This bar passesloosely through a guiding and supporting bracket 22, having a pin 23which may be engaged with either one of two notches 24 in the bar 20,for the purpose of holding the bar 12 in either of its fixed positions.The bar 18 is provided at one end with any suitable actuating means,such as the hand spikes 25. This bar is carried in a series of brackets26 5 (see Figs. 6, 7 and 8), the bar having a journal portion 27 in eachof these brackets. The brackets are in turn lined to a rock shaft 28extending longitudinally of the table. At one end this shaft has acounterweight 29, which normally holds the parts in the positions shownin full lines in the drawings. In this position the portions of the bar18 intermediate adjacent brackets 26 have flat side portions which abutcorresponding surfaces 30 on the brackets 30L attached to the scaleplate 7, as best shown in Fig. 6, and thereby prevent rotation of thebar. When, however, the counterweighted arm 29 is raised to the positionshown in dotted lines in Fig. 5, the movement of the rock shaft 28 willswing the brackets 28 carrying the bar 18 to the position shown indotted lines in said figure. ln this position the bar 18 is free to berotated through an angle of 180. The bar 18 may also be provided with alatch device, consisting of a latch member 31 (see Fig. 8) carried bythe rock shaft 28, and having a flat surface 32 upon which the bar 18rests. At this point, said bar has the rounded surfaces 33 of suchradius that when the bar is turned in the direction of the arrow (seeFig. 8), these curved surfaces will readily ride on the surface 32 topermit of a movement o-f the bar 18 through an angle of 180O only, whena stop is eected by the surface 32. Turning movement in the oppositedirection is, however, prevented. The actuating means for the bars 12and 18 may be located adjacent to each other, as shown in Figs. 1, 2 and3, so that both can be operated at substantially the same time by thesame operator.

The foregoing is a complete description of that part of my invention bywhich the table may be quickly changed from a condition in which o-nesystem of measurements is employed to a condition employing anothersystem. This part of my invention may be used either with or without thefurther improvement next to be described. This feature of my inventionhas relation to a stop or gage which is designed to be used when cuttingwindow or sheet glass to any size or unit obtainable by the spacing ofthe pins in the Ibars 12 and 18, or any fractional part of said spacing.

Ordinarily, the cutting of sheets of fractional sizes is a matter' ofconsiderable difficulty, for which an eXtra charge is made by thecutter.

My'invention provides simple and convenient means whereby fractionalsizes may be cut as readily as non-fractional sizes. The mechanism bywhich this is accomplished will now be described.

The front end of the table is provided with a transversely arranged stopplate 34.- having upwardly extending portions 35 adapted to be projectedabove the surface of the forward edge of the table. This stop plate ismounted upon a series of studs 3G, which engage oblique slots 37 in theplate. When the bar is moved endwise in one direction, (which may bedone by using the knot 34ka as a handle) these slots will cause it to beelevated so as to bring the projection 35 above the edge of the table inthe stopped position for the edge of the glass sheet or plate. l/Vhenthe bar is moved in the oppos site position, the projections will belowered flush with or below the table surface so as to permit the cutsheet to be slid thereover and removed from the table. When the plate 34is set in the normal position, shown in Figs. 1, 2 and 3, and the glasssheets are moved up against the stop projections 35, the cuts made whenthe rule is properly at j listed will be in accordance with one or theother of the scales on the scale plate 7.

To take care of cutting fractional lengths, T provide means whereby thestop plate 34 may be moved toward or away from the end of the table. Forthis purpose, the studs 36, before referred to, are extended inwardly,as best shown in Fig. 11, and are provided with rack teeth 38 engagingpinions 39 on the transverse shaft 4L() (see Fig. 11). Secured to oneend of the shaft 40 is a depending lever arm 41 having two spring catchpins or dogs 42 and 43. Either one of these pins or dogs may be broughtinto operation, the other one being locked out of operable position by apartially rotary movement, as indicated in Fig. 10.

44: is a sector plate adjacent to the lever arm l1 and provided with twosets of perforations L15 and 46. The perfor-ations 15 are arranged to beengaged 'by the pin or dog 42, and the perforations 46 by the pin or dog43. The perfor-ations 45 are spaced for obtaining fractions of an inch,while the perforations 46 are spaced for obtaining fractions of acentimeter. `When, therefore, the lever arm 4l is moved to a certainposition over the sector 44 and one of its spring dogs is engaged withone of the perforations, the stop plate 34 will be moved to an exactlycorresponding position. If, for instance, it is desired to cut a pieceof glass 9% inches in length, the lever arm 41 would be moved over thesector to engage the proper perforation 45 for the inch fraction. Therule being set at the 9 inch indication on the scale and the glass sheetbeing moved up against the top plate, the cut made would be 9J,- inchesfrom the front edge of the sheet. lVhere this feature of my invention isemployed in connection .with an ordinary table adapted to one syst-em ofmeasurements only, the sector plate 44 will, of course, have only oneset of perforations.

It will be obvious that many changes can be made in the details of thispart of my invention within the scope of the appended claims relatingthereto.

If desired, the scale plate 5 may also be provided with the fractionalscales 5a, by which the front edge of the plate may be set independentlyof the stop mechanism just described. A

The advantages of my invention will be apparent to those familiar withthe use of glass cutting tables for window and other sheet glass. At thepresent time some of the orders received by glass manufacturing concernsgive measurements according to the metric system, while others givemeasurements according to the old system. Unless two separate tables areprovided, or the orders are translated from one system into the other,it is dificult to properly lill all such orders. By my system the tablecan be quickly converted in condition for use according to eithersystem. rlhe provision for means for taking care of fractional lengthsintermediate the divisions of the scale plate 7 is also of greatconvenience, and greatly facilitates the work.
